About LSM330 Register Problem

Currently, I am now using LSM330, the only reference driver I found is official Linux-OS driver. Since there's no programming guides, I search website for source code for reference, only to find that all source code I found have a different register definition.

For instance, in a project in github, among the initialization code block, the author wrote the code below:

However, in LSM330 official datasheet, the accelerate motion sensor has no CTRL_REG1, and from the content, we can see that the author disable HPF for ACCEL, where's ACCEL-HPF??? Only gyroscope has two LPF and one HPF.
